Thats great! But equally great is that Green bay, WI has 100,000 people and they sell out 80,000 seats on a regular basis.
Can't compare with a city like DC. What else does one do in Green Bay or all of Wisconsin for that matter on a winter Sunday? You can only do so much ice fishing.
The best part of the Packers is that the team is publicly owned non-profit with 360,000 stock holders, something that sports could use more of.
